Create a Front Panel configuration file with the control definition.
Create the icon for the control. The recommended size is 16 by 16 pixels.
For example, the following control puts a Terminal control in the switch.
CONTROL SwitchTerminal { TYPE icon CONTAINER_NAME Switch CONTAINER_TYPE SWITCH POSITION_HINTS 3 ICON Fpterm LABEL Terminal PUSH_ACTION Dtterm HELP_TOPIC FPOnItemTerm HELP_VOLUME FPanel }
The control uses a built-in icon and the same help topic used by the Terminal control in the Personal Applications subpanel.
